ATTORNEY Patented Feb. 14, 1933 UNITED STATES ARTHUR WARNER, OFHAVERFORD, II?ENNSYLVANIA DEAD-END ATTACHMENT Application filed February7, 1931. Serial No. 514,174.

My device is a means for joining the ends of two or more lines of ropewithout splicing. These lines may be formed from a single rope or fromseparate ropes. My device provides means for looping wire driving ropesto avoid splicing thereby saving in cost and adding to the ease ofmaking loops. It also permits the loops to be of short length andpermits equalizing the length and stress in multiple lines of rope. Mydevice also provides means for tightening the rope to take up the slack.By means of my device two or more lines of rope may be formed intoendless loops. These lines are permitted to flex freely and to bearuniformly upon the tread of a sheave as the rope passes about thesheave.

For a further exposition of my invention reference may be had to theannexed drawing and specification at the end whereof my invention willbe specifically pointed out and claimed.

In the drawing,

Figure l is a top plan view of my device with the sheave broken away.

Figure 2 is a vertical cross section on line 11 of Figure 1, some partsnot being shown in section.

Figure 3 is a fragmentary vertical side elevation on the line 22 ofFigure 1.

Figure 4 is a bottom view of my device, and

Figure 5 is a vertical cross section through a modified form of mydevice.

In the embodiment of my invention, chosen for illustration in thedrawing, my device is shown as consisting of a plurality of lines 4 ofwire driving rope. These lines may be formed from a single rope or fromtwo or more ropes. My improved device consists of a deadend attachment 8which provides means for joining the ends of the lines of rope intoendless loops Without splicing. This is an exceedingly desirable featureas splicing is a costly and difficult operation, especially with wireropes.

The dead-end attachment 8 has on its lower surface a plurality ofgrooves of suitable cross section to permit the lines 4 to flex freelytherein. As is best seen in Figure 2, grooves 20 connect with passages21 which lead away from the lower surface of attachment 8 and connect attheir upper ends with a passage 22 in the opposite end wall of thedead-end attachment. The passage 22 may be in the opposite end wall ormay be in the same end wall as the passages 20 or the passage 22 maylead parallel to the passages 20 in the same end of the attachment 8.There are also provided in the bottom face of attachment 8 passages 23which are also of such cross sec tion that lines 4 are free to flextherein. Passages 23 connect with enlarged passages 24 which lead out ofthe opposite face of attachment 8 or which may be doubled back and leadout of the same end face of attachment 8 from which passages 24 lead. Inother words passages 24 may open out ofthe end face above grooves 20 ormay open out of the opposite end face above grooves 23 in'which case thegrooves 24 are U-shaped in vertical cross section. Passages 24 form aconvenient means for fastening ends of lines 4 so that the lines areanchored in the attachment 8. The ends of lines 4 may be clamped,bolted, zinced or socketed in attachment 8. The ends of lines 4 may berigidly attached to attachment 8 but are preferably fastened so that theends of the lines are movable out of passages 24 but are fixed againstmovement from passages 24 into passages 23.

As is best seen in Figure 4 there may be provided on the bottom ofattachment 8 adjacent passages 21 a throat piece 12 which overliespassages 21 to a certain extent and which serves toretain the lines 4 inthe passages 21 should any slack occur in these lines. Throat-piece 12is attached to attachment 8 in any convenient manner as by a screw 13.

A modified form of attachment of the ends of lines 4 to attachment 8 isshown in Figure 5. This modified form of attachment permits adjustmentof the lines 4 to take up the length of these lines and to equalize thestresses in the lines. These connections consist of sockets 10 to whichthe ends of the A lines 4 are either fastened or so arranged as to beimmovable through the sockets 10. Sockets 10 have threads on their outersur faces with which cooperate nuts 11. These nuts serve to adjust thesockets 10 and there- 1 fore the ends of lines 4 relative to theattachment 8.

In Figure 2 the lines 4 are shown as formed into endless loops by meansof the dead end attachment 8. These loops pass over sheaves 5 which aremounted on shafts 6 and 7 respectively. The lines 4 may, if desired, beconnected together at various points by rope grips 9, to keep themspaced apart.

I do not intend to be limited in the practice of my invention save asthe scope of the prior art and of the attached claims may require.

I claim:

1. A dead end attachment for ropes comprising a body having groovestherein which permit free flexing of a rope in the grooves, meansconnected to a pair of said .grooves for attachinga loop of rope to saidbody, and means for attaching a plurality of rope ends to said body.

2..A dead end attachment for ropes comprising a body having groovestherein which permit free flexing of a rope in the grooves, a grooveconnected to a pair of said first mentioned grooves for attaching a loopof rope to said body, and means for attaching a plurality of rope endsto said body.

3. A dead end attachment for ropes comprising a body having groovestherein which permit free flexing ofa rope in the grooves, means,connected to a pair of said grooves for attaching a loop of rope to saidbody, and flared openings connected to a pair of said first mentionedgrooves for attaching a pair. of rope ends to said body.

4. A dead end attachment for ropes comprising a body having groovestherein which permit free flexing of a rope in the-grooves, means forattaching a loop of rope to said body, openings connected to a pair ofsaid first mentioned grooves, screw sockets in said openings forreceiving acpair of rope ends, and nuts on said screw sockets foradjusting said rope ends relative to said body.

5.. A dead end attachment for ropes comprising a body having groovestherein which permit free flexing of ropes in said grooves,

a groove connected to a pair of said first mentioned grooves forattaching a loop of rope to said body, a throat piece attached to saidbody so as to hold a rope in the connection between said first mentionedand said last mentioned grooves, and means for attaching a plurality ofrope ends to said body.

6. A dead end attachment for ropes comprising a body having grooves inone face thereofwhich permit free flexing of a rope in the grooves, agroove infanother face of saidbody from that containing thefirstmentioned grooves and connected to a pair of said first mentionedgrooves for containing a loop of-rope on said body, and means forattaching a plurality of rope ends to said body.
